Abstract
Description
where
- HT=[h0, . . . , hL]T is a complex-valued vector representing the radio channel of the home cell, Ut=[ut, . . . , ut−L]T is a complex-valued vector representing the transmitted symbols in the home cell,
- GT=[g0, . . . , gL]T is a complex-valued vector representing the radio channel for the CCI,
- Vt=[vt, . . . , vt−L]T is a complex-valued vector representing the transmitted symbols of the CCI, and
- et is noise, which is often assumed to be white noise.
